In a same way - define differential level on the schedule for each day. To understand differential backup and what each level do check official administration guide (used to have nice explanation there illustrated with pictures).

Networker's way of backing up is differential's plus a little more... You have what are known as level backups.

A differential backup is all that has changed since the last full backup. With level backups everything is backed up since the last lower level backup (and for this you have to think of it that a full backup is the same as level 0). The level backups allow you to add a little more complexity to how you back things up.

As a very simple way of doing this you can do a differential like this:

day 1 - full (level 0)
day 2 - level 9
day 3 - level 8
day 4 - level 7
and so on

You could also use level backups to do something akin to incremental backups like so:

day 1 - full (level 0)
day 2 - level 1
day 3 - level 2
day 4 - level 3
and so on

- the same data will be backed up as in an incremental backup, but the media database will record a specific level rather than "incr" (may be useful for some kind of reporting).

If you go on the Networker course there are some nice slides that illustrate this!

I'm thinking the following work's also.
Day1 Full
Day2 level 1
Day3 level 1
Day4 level 1
Day5 level 1 ...

This way makes it easier to setup the schedules.

Matt is correct in what he says; you have to remember that the level backups will backup everything since the last LOWER LEVEL backup; if you are doing a level 1 backup and the previous day was a level 1 that is not lower!

Hi,

            The Differential backup level is used only for the faster restoration , say if you take incremental backup everyday,finally if you want to restore it will take much time and the backup also get splitted into different tape so it also needs the many tapes to restore , where as the Differential backup is having 9 levels , from Level 1 to Level 9 , Level 1 will take backup of changes from last Full backup and Level 2 will take backup of changes from last Level 1 backup or Full Backup , If level 1 backup isnot done then level 2 backup will take last full backup and vice versa . This is the differential Backup .

To configure the differential backup go the schedule and select from Level 1 to 9 depends on the requirement .

Mats solution is differential.

It will backup all changes since last full.

It is Differential only , Differential backup will take the changes of last Full backup or Last level bakup only .
